UNITED STATES PATENT OFFIc GEORGE PITTS AND GEORGE W. MEDBURY, OF PROVIDENCE, R. I.

DETACHABLE BUTTON.

SPEGIFIOATION forming part of Letters Patent No. 242,975, dated June 14, 1881. Application filed April 14, 1881. (No model.)

To all whom tt may concern.-

Be it known that we, GEORGE PITTs and GEORGE W. MEDBURY, of Providence, in the State of Rhode Island, have invented an Improvement in Detachable Buttons, of which the following is a specification.

Our invention relates to that class of detachable buttons where the shoe is hinged to the post, so as to allow the shoe to be turned to one side against the post for the purpose of insertion or removal from the buttonhole; and it consists in the special construction of the post and of the spring which serves to hold the shoe in its proper positions for use.

Figure 1 represents an axial section of the button. Fig. 2 represents a plan view of the inner side of the post as formed up previous to folding. Fig. 3 represents a plan view of the outer side of the same. Fig. 4 represents a central longitudinal section of the same. Fig. 5 represents a central longitudinal section of the post when properly formed by bending, taken at right angles to the hingejoint. Fig. 6 represents a central longitudinal section taken in the line now of Fig. 5. Fig. 7 repre sents a side elevation of the post when completely formed. tion of the spring which serves to hold. the shoe in position. Fig. 9 represents an end elevation of the sliding piece which serves to transmitthe pressure of the spi ing to the hingejoint. Fig. 10 represents a side elevation of the same.

Inthe drawings, Fig. 1, A is the head of the button, and B the post, made hollow to receive the spring 0 and the sliding piece D. The end of the post B is provided with the two ears b 1), shown in Fig. 7.

To the inner side of the shoe E is attached the piece of square hollow wire 6, made to fit within the space between the ears I) b. The shoe E is hinged to the post by means of a I the shoe.

Fig.8 represents a side elevawire passing through the holes a a in the ears b b of the post B and the hole 0 in the square or angular piece of hollow wire 6 attached to The spring 0 forces thesliding piece D downward against the flat sides of the piece 6, thus holding the shoe in the position shown in Fig. 1, at right angles to the post, for locking the button in the button-hole, and also in the position shown by the dotted lines at the side of the post, for ready insertion or removal.

The spring 0 is made in the form of the let-. ter 8, as shown in Fig. 8, and the post B is struck up from the fiat stock, as shown in Figs. 2, 3, and 4, and folded together so as to form a chamber, 9, for the reception of the spring O and the sliding piece D, and also forniinga hole, a, in the resulting ears b Z1, the central portion, h,of the original plate being cut away to form the proper space for the reception of the piece of square or angular hollow wire 6.

The depressions g g, struck in the sheet of stock of which the post is formed, serve to form,

when folded together, the chamber 9 of the post, and the central depressions, a a, likewise serve to form a hole, a, to receive the wire which connects the shoe and post.

The chamber 9 is closed at its upper end by the stone G, or by a separate plate secured over the back plate, H, of the head A, after the in sertion of the spring 0.

We claim as our invention- In a detachable button, the combination of the head A with the hollow post B, provided with the chamber g, closed at its 'npper end, spring 0, sliding piece D, and the shoe E, pro vided with the square or angular piece a, substantially as described.
